Cry It Out vs the Ferber Method

Same goal, different amount of presence

Both methods are built on extinction, which means removing the help a baby is used to falling asleep with, so the baby learns to settle alone. The split is simple. With full extinction, often called cry it out, you do your bedtime routine, put the baby down drowsy but awake, and do not go back in until a set morning time. With graduated extinction, the Ferber method, you do the same setup but return at planned, lengthening intervals to briefly reassure without picking the baby up.

Dr. Richard Ferber popularized the timed-check version, which is why most people call graduated extinction the Ferber method. The check-ins are short, usually under a minute or two, and are meant to reassure you and the baby that nothing is wrong, not to stop the crying. Picking the baby up or feeding restarts the association you are trying to fade.

Ferber progressive-waiting schedule

A common Ferber interval plan in minutes; wait this long before each check, then comfort briefly without lifting the baby. Ranges vary by source, so adjust to your comfort.

Night	First check	Second check	Third check	Later checks
Night 1	3 min	5 min	10 min	10 min
Night 2	5 min	10 min	12 min	12 min
Night 3	10 min	12 min	15 min	15 min
Night 4	12 min	15 min	17 min	17 min
Night 5	15 min	17 min	20 min	20 min

How the two compare in practice

Full extinction is usually the fastest method, often working within a few nights, because the baby gets no intermittent response to hold onto. The hard part is that the crying can be intense and there is no built-in way to check that the baby is okay, which many parents find difficult. The Ferber method tends to be nearly as fast while giving you scheduled moments to lay eyes on your baby, which is why it is the more popular starting point.

One thing to expect with both is an extinction burst, a night or two where crying briefly gets worse before it gets better. That is normal and is not a sign the method failed. Consistency through that stretch is what makes it work; going back to old habits midway can make the next attempt harder.

Evidence on safety

What the research currently shows about both methods:

• Studies of graduated extinction have not found lasting harm to babies' stress hormones, attachment, or emotional development.
• Reviews report no long-term negative effects on children's mental health or their relationships with caregivers.
• Benefits seen in studies include faster sleep onset, fewer night wakings, and improved parent mood and sleep.
• Neither method is recommended before about 4 months; younger babies usually still need night feeds and cannot yet self-soothe.

Which method suits whom

A rough guide to choosing:

• Choose Ferber if you want a fast result but need to check on your baby to stay calm, or if leaving the room entirely feels like too much.
• Choose full extinction if repeated check-ins seem to wind your baby up more, and you can commit to not going in until morning.
• Choose a gentler method instead if any crying feels intolerable, your baby is on the younger end, or your pediatrician advises a slower approach.
• Either way, keep the full safe-sleep setup and a consistent bedtime routine.

Related questions

Is the Ferber method the same as cry it out?

Not exactly. Cry it out usually means full extinction with no check-ins until morning. The Ferber method is graduated extinction, where you return at timed intervals that get longer to reassure your baby briefly without picking them up.

How long does the Ferber method take to work?

Many babies sleep better within about 3 to 7 nights when the plan is followed consistently. Expect a harder night or two at the start, called an extinction burst, before improvement.

Do you pick the baby up during Ferber checks?

No. Ferber check-ins are short, usually under a minute or two, and use voice or a gentle touch to reassure. Picking the baby up or feeding restarts the sleep association you are trying to fade.

At what age can you start cry it out or Ferber?

Most experts suggest waiting until about 4 to 6 months, when many babies can self-soothe and no longer need overnight calories. Check with your pediatrician before starting earlier.
